CORSA is one of the largest automotive and high-end marine exhaust tuning companies in the USA with engineering and manufacturing facilities in Ohio and a patented, proprietary technology called Reflective Sound Cancellation™ (RSC, for short). CORSA consults to General Motors, Ford and Daimler-Chrysler and carries the title of "official licensed product" on its GM aftermarket exhaust systems.
The result of the CORSA's partnership and extensive research and development on the BMW 3 and 5 Series, is the new dronefree RSC™ exhaust system, delivering a pleasant sound at idle and cruise, and a muscular roar at high rpm. CORSA tuned this system specifically to counter drone. Sound pressure waves are reflected within the muffler case and unwanted noise frequencies are cancelled through patented Refective Sound Cancellation™ technology. Their straight-through design coupled with RSC™ noise cancellation technology allows them to tune out the undesirable low frequencies that cause droning, while reducing back pressure. A reduction in back pressure allows the engine to produce more horsepower and torque. The end result is a tuned muffler that produces the best sound and performance possible.
